Short-term and intermediate-term results after unclipping: what happened to primary hyperhidrosis and truncal reflex sweating after unclipping in patients who underwent endoscopic thoracic sympathetic clamping?
Endoscopic thoracic sympathetic clamping (ETC) is used to treat patients with primary hyperhidrosis because it offers the potential of a reversal operation (unclipping) when severe reflex sweating (RS) occurs. Although unclipping has been reported to be effective, the short-term or intermediate-term results after unclipping are unclear. From March 2002 to October 2006, 15 (12.9%) out of 116 patients with primary hyperhidrosis, who underwent ETC, had the endoclip(s) removed as a result of RS. Fourteen patients could be followed up for more than 6 months. The patients answered a telephone interview on the severity of RS, the recurrence of the primary site, and their level of satisfaction. There was no mortality or significant morbidity encountered. On the follow-up, 9 (64%) of the 14 patients who underwent unclipping reported symptomatic recovery from RS. Of these 9 patients with early unclipping (within 4 wk after ETC), only 7 (78%) were satisfied with the outcomes. This suggests that early unclipping does not always guarantee satisfactory recovery from RS. Because early unclipping does not guarantee a full recovery in all patients, special consideration in ETC is needed to determine when to remove the clamp and how strongly to apply the clamp to achieve better results.
